This is an updated XRAY Delrin V3 Shock Piston Set. These are replacements for the XB8 2015 edition and are also backwards compatible with previous models. Package includes pistons for two shocks. Two packages will be required for use in four shocks.

This set includes 8-hole and 10-hole pistons. The 8-hole pistons are available with 2 different sized holes, 1.2 and 1.3mm. The 10-hole pistons are available with 1.1mm holes.

These big-bore 16mm pistons are manufactured from specially-formulated composite material to provide smoother action and durability. With an updated piston mold and well-proven molding processes, XRAY ensures perfect piston roundness after production, so that the pistons move perfectly inside the shock bodies for identical shock action in all four shocks.
